This is a private hackathon open to UmojaHack South Africa participants. If you are a university student in South Africa and would like to participate, contact Zindi Community Coordinator Paul Kennedy.

Ride-hailing apps like Uber and Yassir rely on real-time data and machine learning algorithms to automate their services. Accurately predicting the estimated time of arrival (ETA) for Yassir trips will make Yassir’s services more reliable and attractive; this will have a direct and indirect impact on both customers and business partners. The solution would help the company save money and allocate more resources to other parts of the business.

The objective of this hackathon is to predict the estimated time of arrival at the dropoff point for a single Yassir journey.

Submissions and winning

You may make a maximum of 100 submissions per day. Your highest-scoring solution on the private leaderboard at the end of the competition will be the one by which you are judged.

Zindi maintains a public leaderboard and a private leaderboard for each competition. The Public Leaderboard includes approximately 50% of the test dataset. While the competition is open, the Public Leaderboard will rank the submitted solutions by the accuracy score they achieve. Upon close of the competition, the Private Leaderboard, which covers the other 50% of the test dataset, will be made public and will constitute the final ranking for the competition.

If your solution places 1st, 2nd, or 3rd in the final ranking, you will be required to submit your winning solution code to us for verification and you thereby agree to share all worldwide rights of copyright in and to such winning solution to Zindi.

You will have until 20:29 GMT on 25 July 2020 to submit your code for review. Submit your code to with subject line “UmojaHack South Africa position # - team name or username and university.” Regardless of any public announcement of winners, Zindi reserves the right to disqualify any user, team, or university on or even after 27 June 2020 if the code does not reproduce the winning submission.
